Please how do I solve this problem even if it means flashing a custom stock rom. I also observe there are many people in other forum with this same device and same or similar problem but it seems I got lucky by having access to its exact specifications as stated above which I hope will help in solving the problem.Please help me out.
(26-09-2019, 05:34 PM)amodu Good evening Hovatek
I have acted as instructed but cannot flash because when I click download and plug the phone via usb cable with the battery inserted, I here the connection sound once and disconnection sound once. and the phone lights up with dark screen and remains like that for about one minute after unplug, then goes off.
At the same time I observe the status in the sp research/download tool change from checking baudrate to unplugged, the progress column shows red text "failed: user cancel".
If I remove the battery and connect the phone without the battery, it begins a series of connect and disconnect showing the same info as above in the sp research/download tool until I unplug the usb.
The only time the boot logo displays is when the phone is plugged into a charger. the zero logo displays briefly for 2 seconds only, then the lighted black screen comes on and stays lighted for about 2 minutes before going off after unplug.
Find attached a screenshot of the sp research/download tool during flash
This is the situation report Sir, I earnestly await your help and guidance
(30-09-2019, 03:30 PM)amodu Good afternoon Sir,
I can now connect to spd research /download tool. I do so by first removing and putting back the battery and then press the volume down key while connecting the the phone via usb to the PC
but I get the following error:
Port:7
Step: FDL
Status: Finish
Progress: Failed: The second enumeration port time out
time :1s
Pls help how do I overcome this Sir
(02-10-2019, 07:52 PM)amodu If I connect the phone without holding any key, flashing does not initialize even though the phone comes up with a black lighted screen.
I have installed the research download tool on another pc (windows 7the first one is windows 10 ) including adb /fastboot. I use two different usb cables all new.
I get the same error message and adb does not see my device when I give the command "adb devices"
